---------------------------------------
Thanks [~zabetak] [~amaliujia]. Yes, I am planning to work on this. I will send
to dev@ to have a discussion.
> Implement bit functions and operators
> -------------------------------------
>
> Key: CALCITE-3732
> URL: https://issues.apache.org/jira/browse/CALCITE-3732
> Project: Calcite
> Issue Type: Improvement
> Components: core
> Affects Versions: 1.21.0
> Reporter: hailong wang
> Priority: Major
> Fix For: 1.22.0
>
>
> Bit function is non-standard operators, but all db has implemented, such as
> mysql, postgresql.
> Calcite has implemented BIT_AND, BIT_OR in
> https://issues.apache.org/jira/browse/CALCITE-2770, BIT_XOR in
> https://issues.apache.org/jira/browse/CALCITE-3591. BIT_COUNT is in progress
> https://issues.apache.org/jira/browse/CALCITE-3697, BIT_NOT(~) is in progress
> https://issues.apache.org/jira/browse/CALCITE-3592.
> So I think we should also implement Bitwise AND(&), Right shift(>>), Left
> shift(<<), Bitwise XOR(^), Bitwise OR(|). And data types support tinyint,
> smallint, int, bigint like before.
>
> Refence:
